Answers
Answer:
1. Speed is the distance traveled per unit of time. It is how fast an object is moving.
2. The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time.
3. The viscosity of a fluid is a measure of its resistance to deformation at a given rate.
4. A combination reaction (also known as a synthesis reaction) is a reaction where two or more elements or compounds (reactants) combine to form a single compound (product).
Such reactions may be represented by equations of the following form: X + Y → XY.
5. A single-displacement reaction, also known as a single-replacement reaction, is a reaction by which one element replaces an/other element in a compound. It can be represented generically as: A + B-C → A-C + B
✏️✏️ speed : Speed is the distance traveled per unit of time. It is how fast an object is moving. Speed is the scalar quantity that is the magnitude of the velocity vector. It doesn't have a direction. Higher speed means an object is moving faster.
✏️✏️ velocity: Velocity is a vector expression of the displacement that an object or particle undergoes with respect to time . The standard unit of velocity magnitude (also known as speed ) is the meter per second (m/s). Alternatively, the centimeter per second (cm/s) can be used to express velocity magnitude.
✏️✏️ : viscosity : DescriptionThe viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of "thickness": for example, syrup has a higher viscosity than water.
✏️✏️ combination reaction : DescriptionThe viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of "thickness": for example, syrup has a higher viscosity than water. Wikipedia
✏️✏️ displacement : A displacement is a vector whose length is the shortest distance from the initial to the final position of a point P. It quantifies both the distance and direction of an imaginary motion along a straight line from the initial position to the final position of the point.
